A recent study by Linda A. Wray and colleagues found that having both a postgraduate degree and a heart attack significantly increases the likelihood of quitting smoking among middle-aged adults. The research suggests that higher levels of education help smokers 'learn' from their heart attacks and quit smoking.
A recent study by University of Florida researchers found that less than a week's worth of walking or jogging can help the heart produce enough HSP72 to protect it against damage during a heart attack. Exercise can generate this protective protein, which helps stabilize and refold damaged proteins in the heart.
A study found that despite high awareness of chest pain as a heart attack symptom, many people are unaware of other critical symptoms like arm numbness and shortness of breath. The research highlights the need for targeted education about complex heart attack symptoms to reduce delay in seeking medical care.
A clinical trial testing Azithromycin's effectiveness in preventing recurrent heart attacks found a promising link between the antibiotic and reduced inflammation. Researchers aim to determine if treating patients with Azithromycin for five days after an initial heart attack can prevent future heart attacks.
A new analysis of PURSUIT data reveals women in Latin America and Eastern Europe receive less aggressive cardiac treatment and have higher incidence of heart disease deaths compared to men in similar regions. In contrast, women and men in North America and Western Europe receive comparable treatment and outcomes.
Researchers found that administering the drug immediately improves patient outcomes and may alleviate the need for transfer to larger hospitals. The study's results support earlier use of eptifibatide in smaller community hospitals treating heart attack patients with unstable angina.
